Information has come to light about Nividia's mysterious G72 and G73 graphics chips.

According to an AnandTech report which quotes a number of industry insiders, the G72 and G73 will ship as the GeForce 7200 and 7600, respectively. The 7200 will launch in February 2006, the 7600 a month later.

Past reports have suggested the G72 is a 90nm part - current GeForce 7 series chips are fabbed at 110nm. It has also been said to have an early 2006 ship date, which ties in with the latest information.

Both the G72 and G73 have appeared in Nvidia ForceWare driver releases, the G72 going back to July, though the G73 emerged more recently.

To date Nvidia has released GeForce 7800 GT and 7800 GTX desktop GPUs, and the Go 7800 GTX and Go 7300 on the mobile side. The company is believed to have a 7800 GS desktop part in the pipeline, again according to recent driver contents. A version of the 7800 GTX that supports 512MB of video memory is said to be in the works too.

The AnandTech report's sources claims the 7200 and 7600 can use the same circuit boards as the GeForce 6200 and 6600, respectively, allowing them to roll out boards based on the new chips more easily. ®
